Parameterized Complexity of Odd Domination and its Generalization

Toranosuke Kokai, Rin Saito, Tatsuhiro Suga +2

In the \textsc{Odd Domination} problem, given a graph and a positive integer , the task is to determine whether there exists a vertex subset of such that the closed…

Solution Discovery for Vertex Cover, Independent Set, Dominating Set, and Feedback Vertex Set

Rin Saito, Anouk Sommer, Tatsuhiro Suga +2

In the solution discovery problem for a search problem on graphs, we are given an initial placement of tokens on the vertices of a graph and asked whether this placement can be…

Coloring Reconfiguration under Color Swapping

Janosch Fuchs, Rin Saito, Tatsuhiro Suga +2

In the \textsc{Coloring Reconfiguration} problem, we are given two proper -colorings of a graph and asked to decide whether one can be transformed into the other by repeatedly a…

Reachability of Independent Sets and Vertex Covers Under Extended Reconfiguration Rules

Shuichi Hirahara, Naoto Ohsaka, Tatsuhiro Suga +3

In reconfiguration problems, we are given two feasible solutions to a graph problem and asked whether one can be transformed into the other via a sequence of feasible intermediate…

Changing Induced Subgraph Isomorphisms Under Extended Reconfiguration Rules

Tatsuhiro Suga, Akira Suzuki, Yuma Tamura +1

In a reconfiguration problem, we are given two feasible solutions of a combinatorial problem and our goal is to determine whether it is possible to reconfigure one into the other,…
